CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 313,216, dated March 3,1885.

Application filed August 25, 1884. (No model.)

in the county of Seneca and State of Ohio,

have invented a new and Improved Oar-Ooupling, of which the following isa full, clear, and exact description.

The invention consists in the combination, with a draw-head, of asliding block in the same, on which sliding block a downwardlyswingingpiece is hinged. A tripping-pin is pivoted in a slot in the free end ofthe hinged part, and the lower end of the said pin is connected by alink wit-h the front end of the bot tom of the draw-head.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a longitudinal sectional elevation of our improvedcar-coupling, showing the position of parts when uncoupled. Fig. 2 is aside view of the same, showing parts when coupled. Fig. 3 is a front endview.

The drawhead A, which is hollow and open at its outer end, contains asliding block, B, provided with laterallyprojecting pins 0, passingthrough longitudinal slots D in the sides of the draw-head. The frontpart, E, of the bottom of the sliding block B is hinged to swingdownward, and the movement of the block B in the draw-head is soarranged that the part E can only swing down when the block B is pulledout as far as possible. The swinging part E is provided with twoupwardly-projecting side prongs, F, at the free end, the said prongsfitting in side recesses, G, in the front part of the block B. Theswinging part E is provided in its free end with a longitudinal slot,H,'in which a tripping-pin, J, is pivoted, which has its lower or innerend connected by pivoted links K with the bottom of the draw-head. Thetop and bottom of the draw-head are provided with coupling-pinapertures, and the draw-head A, as well as the swinging part E, isprovided with couplingpin apertures, which, when the block B is pushedentirely into the draw-head, coincide with the pin-apertures in thedraw-head.

The operation is as follows: When the parts are in the position shown inFig. 1 and the car is to be coupled, the pin B rests on the slidingblock B, and is held in the top of the draw-head. The entering link Lstrikes the block B at the inner end of the hinged part E, and pushesthe block into the draw-head, whereby the part E is swung up. When thepin-apertures in the block B coincide with the pin-apertures in thedraw-head, the couplingpin B drops and passes through the link andthrough the hinged part E and the bottom of the draw-head.

To uncouple, the pin R is raised, and when the link A is pulled out itsend catches on the tripping-pin J, which was swung up into the draw-headby coupling the cars, and as the link pulls on the said pin J it pullsout the block B, and the hinged part E of the latter drops as soon asthe block B has been withdrawn as far as possible, whereby the link isreleased entirely.

Having thus described our invention, what v we claim as new, and desireto secure by Letters Patent, is

l. The combination, with the draw-head A, of the sliding block B, thehinged part E, and a tripping-pin pivoted in the free end of the hingedpart and connected by a link with the draw-head, substantially as hereinshown and described. 1 I v 2. The combination, with the draw-head A, ofthe sliding block B, the hinged part E, having a slot, H, in its freeend, the pin J, passed through the slot H and pivoted in the same, andthe link K, connecting the lower end of the pin J with the draw-head,substantially as herein shown and described.

3. The combination, with the draw-head A, having longitudinal sideslots, D, of the sliding block B, provided with side pins, 0, the hingedpart E, the pin J, passed through and pivoted in the slot H in the pieceE, and the link K, connecting the lower end of the pin J with thedraw-head, substantially as herein shown and described.
